[asterisk-users] Re: IAX2 goes "one way audio" when lag gets bad

[Pavel Jezek]

I have same problem, but only with 1.4 branch and when some bigger 
jitter occur (1.2 is working fine, even in case with big jitter),
I dump packets with tcpdump and see, that asterisk stops sending packets 
in one direction...
Maybe good reason to open bug report for this, because QoS settings ins 
not always possible (e.g. my case with CDMA connection)
